當我嘗試調試時，go build參數包含-gcflags "all=-N -l"，然后我導入net/http，然后構建將失敗。我嘗試使用 brew 重新安裝 golang，但不起作用。并在卸載后嘗試使用官方安裝，不工作。我正在嘗試sudo mv /Library/Developer/CommandLineTools CommandLineTools.old && xcode-select --install，不工作。在 JimB 的建議下，我嘗試go env -w CGO_ENABLED=0了 ，以便我可以正確構建。有什么建議么？構建失敗消息：# crypto/x509In file included from /usr/local/Cellar/go/1.14/libexec/src/crypto/x509/root_cgo_darwin.go:17:In file included from /System/Library/Frameworks/Security.framework/Headers/Security.h:31:/System/Library/Frameworks/Security.framework/Headers/SecItem.h:452:49: error: expected ','    API_AVAILABLE(macos(10.7), ios(NA), bridgeos(NA));                                                ^    ......                                                ^In file included from /usr/local/Cellar/go/1.14/libexec/src/crypto/x509/root_cgo_darwin.go:17:In file included from /System/Library/Frameworks/Security.framework/Headers/Security.h:35:/System/Library/Frameworks/Security.framework/Headers/SecImportExport.h:317:55: error: expected ','          API_AVAILABLE(macos(10.7), ios(NA), bridgeos(NA));                                                      ^    ....../System/Library/Frameworks/Security.framework/Headers/SecImportExport.h:656:49: error: expected ','    API_AVAILABLE(macos(10.7), ios(NA), bridgeos(NA));                                                ^    ......27 errors generated.package mainimport "os"func main() {    println(os.Args)}> go build main.go                       # success> go build -gcflags "all=-N -l" main.go  # success--------------------------------------package mainimport "net/http"func main() {    println(http.DefaultClient)}> go build main.go                       # success> go build -gcflags "all=-N -l" main.go  # fail       <-----------
